To all whom it may concern Be it known that l, HARRY C. WAITE, a citizen of the United States, residing at West Pullman, Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Gearing for Motor-Vehicles, of which the following is a specification.

My invention relates to improvements in gearing designed for use on motor-driven vehicles, particularly vehicles of the type of agricultural tractors.

The object of the invention. is to provide a transmission gearing suitable for such service and in which means is provided for driving external machinery from the vehicle motor, the clutch and change speed and reverse gearing of the vehicle being also used to control the movements of the said external driving means.

My invention will be more readily understood from the accompanylng drawings, in

which Figure 1 is a plan view of the central portion of the chassis frame of an agricultural tractor, showing the general relation to the partswhich constitute the subject-matter of my invention. Fig. 2 is an enlarged sectional view through the transmission housing of Fig. 1, and Fig. 3 is asection taken on the line 3 of Fig. 2 and showing the way in which the control rods for the transmis- Referring more parti laily. to the drawings, the numeral 10 designates-the chassis frame and the numeral 11 the sub-frame of the vehicle in which the engine and transmission are mounted. The engine which is shown in the drawing as an internal combustion engine and designated by the numeral 12, is mounted longitudinally of the directly to the rear axle of the vehicleor to a jack-shaft from which the rear wheels are driven.

It is the particular object of the present invention to provide a. means by which the driven members of the transmission gearing, located within'the housing 16, may actuate a transversely-arranged shaft 18 which extends beyond the chassis frame 10 and carries external drive means, such as the pulley 19, on its projecting end, whereby the motor 12 may be used to actuate external machinery, such as threshers, choppers, or the like, the clutch 14 and transmission gearing within the housing 16 being made to control the operation of such driven machinery. One method of accomplishing this result is to make use of the form of transmission gearing illustrated in detail in Fig. 2. From this view it will be seen that the driveshaft 15 enters the forward end of the transmission housing 16 and just within this end carries a driving gear 20, the outer ends of the teeth of which, designated by 21, are intended to form clutch members as will later appear. The (gear 20 is in mesh with a driven gear .22 keyed upon a lay-shaft 23 which is mounted arallel with the driveshaft 15. The sha 24, which is known as the second speed gear, and gears 25 and 26, known respectively as first speed and reverse gears. Parallel with thelay-shaft 23 and in alinement with. the drive-shaft 15 there is mounted a connecting shaft 27 which extends between the drive-shaft 15 and propeller shaft 17, being provided with bearings in each of these shafts. Splined u on the connecting shaft 27 there is a slidab e gear 28 which is adapt ed to be brought into mesh with the secondspeed gear 24,0f the lay-shaft in one position and in another position is adapted to have internal clutch teeth 29 formed thereon brought into engagement withfthe clutch teeth 21 of the driving gear 20. Behind the sliding gear 28, there 1s a second sliding gear 30 which, in one position is adapted to engage the first-speed gear 25 of the lay-shaft and a smond position is adapted to engage a reverse pinion 31' mounted below and normall in mesh with the reverse gear 26 of the ay-shaft. Beyond the slidin gear 30 there is a third sliding member 32 ormed as a rearwardly facing bevel gear carrying an extended hub 33 provided with internal clutch teeth, which are adapted to be moved into or out of engagement with external clutch teeth 34 formed on the end 35 of the propeller shaft 17. The shaft 18 enters the transmission gear housing 16 at its rear end adjacent the bevel gear 32 and carries a bevel pinion 36 with which the bevel gear is I adapted to mesh when it is moved to disengage itsclutch teeth from the teeth 34 of the propeller shaft 17.

For shifting the slidable gear 28 a shifter arm 37 of ordinary construction is provided which is-mounted upon a tubular shifter rod 38 which extends through a bearing in the front end of the housing 16 and is provided with annpstanding car 39 (see Fig. 3) for the attachment of a control rod. Within the tubular shifter rod 38 there is mounted a second shifter rod 40 which carries an arm The operation of my improved gearing is as follows: When the tractor, or the like vehicle, is being operated as such, the bevel gear 32 will occupy the position in which t is shown in Fig. 2 of the drawings, servmg then as a connectoror clutch member umting the shaft 27 with the propeller shaft The clutch 14 and the change-speed I gearing will then be operated in the usual to the bevel gear ing, speed 'and'the direction 0 manner to control the forward and reverse movements of the tractor. When it is de sired to use the motor of the tractor as a driving means for some external machinery,

the tractor will be maneuvered into theproper positlon, the external ulley 14 will it 1s desired shifter rod 43 connected 32 will. be operated as by some suitable hand-lever to move this bevel gear and its connected clutch to the rear, whereby the clutch will be disengaged from the propeller shaft 17 and the gear 32 brought into mesh with the pinion ,36. The motor clutch 14 and the transmission gearlng will then be operated in a well-understood manner to control the sto ping, 'start rotation of the pulley 14 and through it of the machine which it drives. When it is again desired to use the tractor or the like as a vehicle be bolted to the machine whic to drive, and the the rod 43 will againbe shifted to bring the a of the drawin bevel gear 32 to the position shown in Fi 2 It will thus be seen t at by a very simple change in a standard form of transmission gearing the same has been adapted to the purposes of the resent invention, the combination as a w ole acting to permit of driving an external. machine clutch interposed and at right-angles to from the vehicle motor in the simplest possible manner, retaining all of the advantages of the ordinary form of clutch and transmission.

While I have shown and described in considerable detail one specific embodiment of my invention, it is to be' understood that such showing and description is illustrative only and for the purpose of making my invention more clear, and that I do not regard the invention as limited to thesespecific details of construction, except in so far as such limitations are included within the terms of the following claims, in which it is my intention to claim all novelty inherent in my invention as broadlyas possible in view of the prior art.
